Sci Total Environ 2022 Jun 22:156884. Epub 2022 Jun 22.

College of Biotechnology and Bioengineering, Zhejiang University of Technology, Hangzhou 310032, China.

The potential health effects of microplastics (MPs) have become a public concern due to their ubiquitous in the environment and life. Numerous studies have demonstrated that a high dose of MPs can adversely affect gastrointestinal health. However, few studies have focused on the impact of microplastics on patients' health with respect to gastrointestinal diseases. Read More

Epigenomic analysis reveals a dynamic and context-specific macrophage enhancer landscape associated with innate immune activation and tolerance.

Genome Biol 2022 Jun 24;23(1):136. Epub 2022 Jun 24.

Chinese Academy of Medical Science Oxford Institute, University of Oxford, Oxford, UK.

MiRNA-Based Therapies for the Treatment of Inflammatory Bowel Disease: What Are We Still Missing?

Inflamm Bowel Dis 2022 Jun 24. Epub 2022 Jun 24.

IBD Referral Center, Gastroenterology Department, Careggi University Hospital, Florence, Italy.

Micro-RNAs (miRNAs) are noncoding RNAs usually 24-30 nucleotides long that play a central role in epigenetic mechanisms of inflammatory diseases and cancers. Recently, several studies have assessed the involvement of miRNAs in the pathogenesis of inflammatory bowel disease (IBD) and colitis-associated neoplasia. Particularly, it has been shown that many members of miRNAs family are involved in the pathways of inflammation and fibrogenesis of IBD; therefore, their use as inflammatory and fibrosis biomarkers has been postulated.

Appendix and Ulcerative Colitis: a Key to Explaining the Pathogenesis and Directing Novel Therapies?

Inflamm Bowel Dis 2022 Jun 24. Epub 2022 Jun 24.

Centre of Excellence for Gastrointestinal Inflammation and Immunity Research, University of Alberta, Edmonton, AB, T6G 2X8, Canada.

The vermiform appendix is generally considered a redundant organ, but recent evidence suggests that the appendix could contribute to the pathogenesis of inflammatory bowel diseases, in particular ulcerative colitis (UC), and may even have a therapeutic role; however, mechanisms of the appendix involvement remain unclear. Here, we highlight current evidence on the link between the appendix and UC and consider plausible therapeutic implications. A literature search was conducted using PubMed and PubMed Central from inception to Nov 2021 using the terms "Appendix", "UC", "Appendix & UC," "Appendectomy", and "Peri-appendicular patch," including only articles published in English.

Retroperitoneal and iliopsoas abscess as Crohn's disease onset mimicking a common lumbosciatic pain.

Ann Ital Chir 2022 Jun 15;11. Epub 2022 Jun 15.

Crohn's Disease (CD) refers to a chronic transmural bowel inflammation affecting a range between 5 and 15 per 100,000 person-years worldwide 1. In patients with stricturing CD, the transmural pattern of inflammation may trigger the development of sinus tracts able to connect to other tissues, leading to the formation of fistulas or abscesses 2. Intra-psoas abscesses are rare, affecting between 0. Read More

Short-Term High-Fat Diet Fuels Colitis Progression in Mice Associated With Changes in Blood Metabolome and Intestinal Gene Expression.

Front Nutr 2022 7;9:899829. Epub 2022 Jun 7.

Health Sciences Institute, China Medical University, Shenyang, China.

Clinical cases and animal experiments show that high-fat (HF) diet is involved in inflammatory bowel disease (IBD), but the specific mechanism is not fully clear. A close association between long-term HF-induced obesity and IBD has been well-documented. However, there has been limited evaluation of the impact of short-term HF feeding on the risk of intestinal inflammation, particularly on the risk of disrupted metabolic homeostasis. Read More

Cureus 2022 May 21;14(5):e25177. Epub 2022 May 21.

Medicine, Jinnah Hospital, Allama Iqbal Medical College, Lahore, PAK.

Pyoderma gangrenosum (PG) is a very rare, non-infectious, progressive inflammatory condition falling under the umbrella of neutrophilic dermatoses. It is an ulcerative condition with a wide variety of cutaneous manifestations and multiple clinical variants (classic ulcerative, pustular, bullous, and superficial granulomatous). Additionally, owing to similar patterns of mucocutaneous ulceration, it has certain overlaps with other neutrophilic diseases frequently observed in clinical practice. Read More

The Effect of Pregnancy and Inflammatory Bowel Disease on the Pharmacokinetics of Drugs Related to Inflammatory Bowel Disease-A Systematic Literature Review.

Pharmaceutics 2022 Jun 11;14(6). Epub 2022 Jun 11.

Department of Clinical Pharmacy and Pharmacology, University Medical Center Groningen, 9713 GZ Groningen, The Netherlands.

Due to ethical and practical reasons, a knowledge gap exists on the pharmacokinetics (PK) of inflammatory bowel disease (IBD)-related drugs in pregnant women with IBD. Before evidence-based dosing can be proposed, insight into the PK has to be gained to optimize drug therapy for both mother and fetus. This systematic review aimed to describe the effect of pregnancy and IBD on the PK of drugs used for IBD. Read More

Multi-Strain-Probiotic-Loaded Nanoparticles Reduced Colon Inflammation and Orchestrated the Expressions of Tight Junction, NLRP3 Inflammasome and Caspase-1 Genes in DSS-Induced Colitis Model.

Pharmaceutics 2022 May 31;14(6). Epub 2022 May 31.

Department of Nutrition and Clinical Nutrition, Faculty of Veterinary Medicine, Zagazig University, Zagazig 44511, Egypt.

Gut modulation by multi-strain probiotics (MSPs) is considered an effective strategy for treating inflammatory bowel disease (IBD). The combination of nanomaterial-based MSPs can improve their viability and resistance and can allow their targeted release in the gastrointestinal tract to be achieved. Thus, our aim is to investigate the prospective role of MSP integration into nanomaterials (MSPNPs) and the underlying molecular mechanisms supporting their application as an alternative therapy for IBD using a colitis rat model.

Long-Term Dietary Patterns Are Reflected in the Plasma Inflammatory Proteome of Patients with Inflammatory Bowel Disease.

Nutrients 2022 Jun 17;14(12). Epub 2022 Jun 17.

Department of Gastroenterology and Hepatology, University Medical Centre Groningen, University of Groningen, Hanzeplein 1, 9713 GZ Groningen, The Netherlands.

Diet plays an important role in the development and progression of inflammatory bowel disease (IBD, comprising Crohn's disease (CD) and ulcerative colitis (UC)). However, little is known about the extent to which different diets reflect inflammation in IBD beyond measures such as faecal calprotectin or C-reactive protein. In this study, we aimed to unravel associations between dietary patterns and circulating inflammatory proteins in patients with IBD. Read More
